Y., assignor to Ainsworth Dyeing Machine Company, Utioa, N. Y., a corporation of New York Application May 27, 1936, Serial No. 82,059 '11 Claims. (01. 68-203) This invention relates to a dyeing machine.

Briefly described, my invention involves two sources of dye having dye applying means together with intermediate means for varying the path of the yarn which is being dyed and speed regulating adjustable mechanism for intermittently lifting the yarn from the respective dyeing applicators. I

Probably the primary feature of my invention may be said to reside in the mechanism which is capable of coloring a strand of yarn in many diiferent patterns. For example, the yarn may be alternately colored in two different colors, these colors appearing in either equal or different lengths. Or the colors may be alternately disposed, as just explained, with more or less of the original yarn, usually white, appearing between every other color or every sequence of colors as desired. Additionally, there are many other color combinations which may be created by use of my novel mechanical arrangement.

Further advantages will become apparent as the description proceeds.

In the drawings:

Fig. 6 is a longitudinal sectional view through Fig. 5.

Fig. 7 is a perspective view illustrating one of the adjustable yarn eyelet members.

Like numerals refer to like parts throughout the several views.

Referring particularly to' Figs. 1 and 2, numerals Ill and II indicate the end ormounting plates. These plates carry spaced reservoirs I2 and I3 between them. Each reservoir has an opening |5 therein through which an absorbent disk I6 extends, this disk preferably being of felt and being shaped as shown in Fig. 3. Each disk I6 is detachably mounted upon a shaft ll, carried by the bearing member l8. The shaft has a worm gear I9 which is driven by the worm 20 on a shaft 2|. The shaft 2| is revolubly mounted in bearings 31 and 38 on the end plates Ill and II, respectively.

A suitable housing 22, see Figs. 1 and 4, conceals the driving mechanism just described. It is to be understood that the shaft 2| drives both disks l6 through similar driving mechanism. Each of the disks l6 rotates and dips into the fluid dye 23, see Fig. 3, and carries it upwardly whereby the yarn may contact thereagainst.

Theend mounting plate Ill carries extensions 26 and 21 which act as bearings for a shaft 28. The shaft 28 carries'beveled gears 29 and 30. The end plate III also has a bearing member 3| which acts as one-end bearing for the shaft 40, the other end bearing 32 being'formed on the end plate II, see Fig. 1. The shaft 40 carries a beveled gear 33 which meshes with the beveled gear 29 and thus the shaft 40 drives the shaft 28.

A shaft 4| is located in a bearing 34 on the end plate In and a bearing 35 on the end plate II. This shaft 4| carries a beveled gear 36 which meshes with the beveled gear 30 and thus the shaft 4| is'rotated. Preferably the construction is such as to cause the shafts 40 and 4| to be driven at the same speed.

The shaft 40 carries a gear 42 which meshes with an idler gear 43 to drive a gear 44 attached to the shaft 2|.

The shaft 40 carries a sprocket wheel which drives the speed mechanism 5|! whereby the yarn carrying spindle 5| is caused to rotate at an ad-' justable but constant speed thus pulling the yarn 25 through the machine at a constant speed. The shaft 40 is driven by any suitable means.

Each of the shafts'4ll and 4| carries a double vaned construction which consists of a spoollike member 52 circumferentially adjustably attached by means of a screw 53 onto its respective shaft, see Fig. 6. Curved vanes 54 are pivoted upon the pin member 56, having the enlarged head 51, and a locking nut 58. It will be understood that adjustment of the nut 58 causes movement of the head 51 either against or away from the vane 54 thus looking it in the desired position or else loosening it for movement to the desired position.

As shown in Figs. 1 and 4, studs 60 extend upwardly from the casings 22 and pass through openings 64 in the journals 63 of eyelet members 65. An eyelet 66, having a tapered entering slot 61, is formed as shown in Fig. 7. Winged nuts 68 thread onto the studs 60 and contact the eyelet members 65 to hold them in their adjusted position.

As is shown in Figs. 1 and 2, my construction is provided with bracket means 10, adjustably attached at ll, to control the angle of the yarn entering the machine.

As is shown in Fig. l a bracket member 15 is adjustably connected at 16 onto the reservoir I2. The bracket 15 adjustably carries mechanism 11, this mechanism serving to tension the yarn 25 and to cause it to properly pass through the, dyeing mechanism.

The operation of my device is easily understood. The conical spindle member 5| pulls the yarn 25 through the machine at a constant rate of speed.

The shaft 40, driven by the prime mover, drives I the gear mechanism 50 through the sprocket chain 46 and its associated gear wheels and likewise drives shaft 4| through the cross shaft 28 and its associated gears. Thus, the shafts l and 4| rotate at a constant speed.

The center shaft 2| is driven through the gears 42,13 and 44 and thus the felt washers ii are rotated to carry the lye upwardly whereby contact between the yarn 25 and the felts it cause dyeing to occur.

The vanes 54 are angularly adjusted to the desired position and the spools 52 are circumferentially adjusted upon their respective shafts. The vanes 54 contact the yarn andraise it from 'contact with the associated felt it whereby the dyeing of the yarn is interrupted.

The adjustable vane construction, located on the shaft 40, see Fig. 4 of the drawings, raises the yarn 25 from the felt disc It at certain periods whereby the yarn is maintained free from dye at certain regular spaces. Similarly, the vane mechanism of the shaft ll raises the yarn 25. from the other felt disc Hi. In order'to properly synchronize the application of dye on the yarn 25 the eye members are turned and locked in any desired adjusted positions, see Fig. 1, whereby the dye applied from one felt will be in a properly spaced linear relationship on the yarn with respect to the dye applied from the other felt.

Furthermore, the double vaned lifting mechanism serves to permit the yarn to be raised practically continuously, if desired, whereby the yarn may have extremely short dyed portions. be apparent that many different dyeing combinations may be had.

The shaft 2| drives both of the felt discs l6 similarly and thus a proportioned amount of dye is lifted from each of the reservoirs.

The same driving means which drives the shaft 2i also drives the synchronized lifting means. Furthermore, the two sets of vaned lifting means are timed or synchronized with respect to the speed of the conical roller 5! inasmuch as the length of the yarn dyed is a function of both the speed of the yarns movement and the rotative speed of the vaned lifting means.
